I woke up this morning and found one of my chicks half out of the shell and dead, it looks like its head got stuck and it suffocated. I hate when they get that far and don't make it, so I decided to intervene. After two pecked an opening and got no farther and the peeps got fainter I started to peel away the shell carefully, they seem very dry. I didn't pull the shell completly away I could see their beaks and they were alive and moving so I left them alone, not sure if the yoke had been fully absorbed. It's been about two hours and I went to check on them and no further progress. They are still alive but there is some bleeding, I think from the mother hen stepping on them, should i break them free or leave it alone? Plus all the other eggs that were peeping from inside the shell have not punched through and are silent. I don't want to lose all the chicks this late either by interfering or not any advice? I'm temped to put them in the oven so I can watch them without stressing out the hen, we had a successful hatch that way last year and I'm afaid they will be damaged in the nest now that I have messed with the shell. Is it a bad idea to poke the other air pockets on the ones that were peeping and are now silent?
